Answer:

x = 23 , y = 7 , z = 11

Step-by-step explanation:

Since the triangles are congruent then corresponding sides and angles are congruent , then

PS = CH , that is

2x - 7 = 39 ( add 7 to both sides )

2x = 46 ( divide both sides by 2 )

x = 23

∠ R = ∠ F = 90° , that is

13y - 1 = 90 ( add 1 to both sides )

13y = 91 ( divide both sides by 13 )

y = 7

Then

The sum of the 3 angles in Δ PRS = 180° , that is

∠ S + 90° + 28° = 180°

∠ S + 118° = 180° ( subtract 118° from both sides )

∠ S = 62°

Now ∠ H = ∠ S , that is

6z - 4 = 62 ( add 4 to both sides )

6z = 66 ( divide both sides by 6 )

z = 11

answer:

90 degrees + 28 degrees= 118 degrees

180-118= Z is 62 degrees

13y-1 = 24                                     2x-7 = 39

+1           +1                                          +7     +7

13y = 25                                          2x = 46

/13      /13                                           /2     /2

y = 1.92                                            X = 23

Anyone know the answer to to this algebra question?
liraira [26]

Answer:

a=1

b= 1/16

c= 1/256

d= 1

e= 4/9

f= 16/81

Step-by-step explanation:

Plug in the values of X on the left side of the table into the function on the right side of the table. Remember that negative exponents mean the number is under a fraction. 4^-0 is like saying one over 4^0.

For the blue table, because the numbers are already in a fraction and in parentheses, you apply the exponent to each number individually.

1. What does it mean that Nikoleta is in the 10th percentile for length and weight? Is that a desirable statistic if she was in
VladimirAG [237]

Explanation:

1. It means that Nikoleta is longer and heavier than 10% of children her age.

2. We generally expect that a change from being in the 50th percentile to the 10th percentile signifies a condition that is interfering with normal growth. That is not usually considered desirable.
